THOMAS H. WILLSON, OF SEATTLE, "WASHINGTON.

PORTABLE RADIATOR.

Application filed January 13, 1925. Serial No. 2,206.

To all whom it may concern:

Be it known that I, THOMAS H. lVrLLsoN, a citizen of the United States, residing at Seattle, in the county of King and State of \Vashington, have invented a certain new and useful Improvement in Portable Radiators, of which the following is a specification. v

My invention relates to improvements in portable electric radiators of the hot water type and the object of my invention is to provide a portable electric radiator having on the top thereof an expansion chamber that also serves as a radiator shield or covr for the radiator.

Other and more specific objects will be apparent from the following description taken in connection with the accompanying drawings.

In the drawings Figure 1 is a view in side elevation of a portable electric radiator constructed in accordance with my invention parts being broken away.

Fig. 2 is an end elevation of the same.

Referring to the drawings, throughoutwhich like reference numerals designate like parts, 5 designates a radiator of the ordinary hot water type and 6 designates, in a general way, the external housing of an electric water heater that is connected with the lower portion of radiator 5'by a pipe 7 and with the upper part of radiator 5 by another pipe 8.

9 is a relatively long expansion chamber that is arranged to rest upon the top of the radiator 5 and is connected by a pipe 10 with the lower portion of that end of said radiator opposite to the one with which the electric heater 6 is connected. A removable plug 11 is provided in the top of expansion chamber 9 through which water may be introduced into the radiator.

The radiator 5 is preferably but not necessarily filled substantially full of water but the expansion chamber 9 is preferably left empty or substantially empty except for air that may be contained therein. As the radiator becomes hot and the water therein expands the water or water vapor may expand into the expansion chamber 9 this relieving pressure and obviating any danger of damaging the radiator.

In addition to its function of relieving pressure the expansion chamber 9 also acts as aradiator shield for deflecting the heat sidewise and preventing an excess amount of said heat from radiating directly upward from the radiator.

The expansion chamber, being connected by pipe 10 with the lower part of radiator 5, which is necessarily the coldest part, will not become filled with hot vapor unless the entire radiator is thoroughly heated.

The radiator does not need to be full of water but will operate eficiently as long as there is any substantial amount of water in the same the electric heater causing the heated water to be jetted upwardly after the well known manner of a coffee percolator whenever said heater is energized and there is water present in the same.

The foregoing description and accompanying drawings clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that numerous changes may be made within the scope and spirit of the following claim.

I claim:

In a device of the class described, a radia tor, electric water heating means connected at two points at different elevations with one end of said radiator, means on the top of said radiator forming a combined expansion chamber and radiator shield, and a conduit' pipe connecting said expansion chamber with the lower portion of said radiator.

In witness whereof, I hereunto subscribe my name this 29th day of December A. D;

THOMAS H. IVILLSON.
